Fractional distillation is the most common industrial separation process. Because distillation uses significant energy for both heating and cooling, it can account for half or more of a particular plant's entire operating costs. It's important to save on the capital equipment of a new distillation plant or an expansion project. Buying previously owned, aka used or second hand, distillation columns saves capital.
Another reason to consider buying used or second hand distillation columns is that the most effective ways to reduce distillation operating costs are through process optimization and control techniques, such as measuring differential pressure, not by buying newly manufactured columns.
IPP's stock of fractionation columns were used in a wide array of applications such as solvent recovery columns in Benzene, Toulene, Styrene, VCM plants, purification columns and light alcohol distillation columns in specialty chemical plants, steam stripping columns in the agrichemical/fertilizer industry at ammonia, urea, and di-methyl amine (DMA) plants, in VOC scrubbing systems for removing unreacted olefins and hydrocarbons found at PET plants and high vacuum batch distillation processes among others.
